Abstract: A top closure arrangement for a container having opposed pairs of major and minor side wall panels forming a tubular structure and including opposed pairs of inner and outer closure flaps joined to upper end edges of the side wall panels with the inner closure flaps each having foldably joined to opposite sides thereof support tabs formed from material cut from adjacent portions of said outer closure flaps and folded downwardly for engagement with adjacent surfaces of related side wall panels to help support the inner closure flaps when they are in a closed position.

Abstract: A composite receptacle, such as bulk bin, including an outer container formed from a unitary blank of foldable paperboard, and including four side wall panels foldably joined to each other to form a collapsable, tubular, outer container adapted to hold four separate, replaceable, collapsible, tubular, cellular, inner units each of which is formed from a unitary blank of foldable paperboard and includes a pair of triangular cells.

Abstract: A one-piece, open top, tray type container having flanges on the end walls which engage upper portions of the side walls to form an interlocking connection therebetween which does not require outside securing means.
